Evaluación nutricional e indicadores de grasa visceral y subcutánea en niños con síndrome de Down

Abstract

[eng] Background: There are only few publications related to body composition in Down syndrome(DS).Objective: Evaluate the relationship between indicators of nutrition assessment by Catalanreferences and CDC/NCHS and indicators of body composition, and compare the concordancebetween weight/height index (WHI), body mass index/age (BMIa) and weight/age (WA) toevaluate nutritional status in children with DS.Materials and methods: Analytical cross-sectional study in which 40 children with DS, 20 girlsand 20 boys between 3 and 13 years old were studied. Anthropometric measurements wereperformed to obtain indicators of nutrition assessment as WHI, BMIa and WA and indicators ofsubcutaneous and visceral fat and muscular compartment. Correlation tests and Kappa indexwere evaluated to establish relationship and agreement respectively.Results: The nutrition assessment in children with DS shows that 60% presents overweight andobesity according to BMIa, and 75% according to WHI. Correlation analysis indicates that waistcircumference, fat brachial area, % fat mass by Slaughter and Weststrate and Deurenberg havea high positive correlation with BMIa (P-value < 0.05). A logistic regression model showed thatno indicator of fat mass is clinically significant in predicting an increase of the indicator WA.It was determined that the BMIa and WHI indicators have a higher concordance (Kappa = 0.59;P = 0.0000).Conclusions: We determined a high correlation between nutritional diagnosis (BMIa and WA)with indicators of visceral fat (waist circumference) and subcutaneous (% fat mass and fatbrachial area) in children with DS. A greater agreement was found between indicators of BMIaand WA suggesting that they are optimal for assessing the nutritional status.© 2015 Fundació Catalana Síndrome de Down.
